PIX3L PLOTT3R is a series of printing robots made with LEGO MINDSTORMS EV3s by Sanjay and Arvind Seshan. Different versions provide different features. Some feature a paper feeder, some feature LEGO markers and some feature multiple EV3s working together (Holiday Card Plott3r). Some are programmed in Python and others in EV3-G. Each version also features a different print mechanism.
The original PIX3L PLOTT3Rs from 2016 used parts not available in either MINDSTORMS sets (313131 and 45544), making it hard for others to complete the same project. SCRIB3 is the newest member of the PIX3L PLOTT3R family of robots. It is built with parts available in a single 31313 set. An image processing step is completed in Python to create an image compatible with the EV3. However, the robot uses standard EV3-G code to print.
